For an example for the outputter system, look [here](https://github.com/mattmb/salt-cloud/blob/454b33fc7d1e7edf5e785be83e7fc4d4203eede5/saltcloud/cli.py#L111).

Also, no output should be done in `saltcloud.cloud`. `saltcloud.cloud` should return data which should be displayed in `saltcloud.cli`. This allows proper API access to salt-cloud.
